Managed to find a decent 1/6 scale stl file on the interweb, here's my scaled up 1/4.2 rough version to see if it's viable. It's not looking too shabby at the moment. I'll have a look when it's finished before I commit the time & filament to a higher resolution version.

I'm not going to use the face, well I don't think so but the helmet is spot on for my needs. High resolution version next weekend it is then
